What is the prove that all atoms contain electron?
Answers
Answer:
The proof is the definition of an atom. If, for example, you were to remove all of the electrons from an atom (which would in many cases take a tremendous amount of energy), what you would have left would not be an atom. In the case of hydrogen, which is a proton orbited by an electron, removing the electron produces, not hydrogen, but a naked proton. In the case of Helium, the second element, it contains two protons and two neutrons in the nucleus, orbited by two electrons. If we remove one of those electrons, what we call the resulting two protons, two neutrons and one electron, a helium ion. BUT, if we remove BOTH electrons we no longer have an atom — by definition. We have a bare nucleus, which in the case of Helium is called an alpha particle. Similarly, the simple answer is, if it has no electrons, then it’s not an atom.
